Microfilm is a method of storing documents and images on very small film rolls. This technology allows large amounts of information to be condensed into a compact format, making it easier to preserve and store. Microfilm is often used in libraries and archives to keep historical records, newspapers, and other important documents safe from physical deterioration. To access the information on microfilm, specialized machines called microfilm readers are used. These devices magnify the tiny images on the film, allowing users to view and read the content. Microfilm has been an important tool for researchers and historians, providing access to materials that might otherwise be lost over time.
